Objective: Depression and anxiety are associated with poor outcomes following spine surgery. However, the influence of these conditions on achieving a minimal clinically important difference (MCID) following lumbar spine surgery, as well as the potential compounding effects of comorbid depression and anxiety, is not well understood. This study explores the impact of comorbid depression and anxiety on long-term clinical outcomes following surgical treatment for degenerative lumbar spondylolisthesis.

Objective: Myelopathy in the cervical spine can present with diverse symptoms, many of which can be debilitating for patients. Patients with radiculopathy symptoms demonstrate added complexity because of the overlapping symptoms and treatment considerations. The authors sought to assess outcomes in patients with myelopathy presenting with or without concurrent radiculopathy.

Article Synopsis
  • The study explores how discrimination affects pain interference and treatment among Black and White U.S. adults.
  • Black participants reported a 41% increased likelihood of pain interference related to moderate and high discrimination, whereas White individuals experienced a 21% increase with moderate discrimination.
  • Both racial groups faced reduced chances of receiving pain treatment when they had experienced discrimination during job searches, highlighting a significant impact on healthcare access.
  • The findings stress the need for effective strategies to address the adverse effects of discrimination on health outcomes and promote health equity.

Hashimoto's encephalopathy (HE), a rare immune-mediated disorder, manifests as altered mental state, cognitive and psychological dysfunction, seizures, and myoclonus. Little is known, however, about the neuropsychological profiles of individuals with HE due to the sparse amount of research. This report overviews HE, summarizes findings from available published neuropsychological evaluations, and details neuropsychological examinations of a 57-year-old White woman with a confirmed HE diagnosis evidencing persistent neuropsychological impairment at two discrete timepoints.

Background: Previous data on the prevalence of unruptured intracranial aneurysms (UIAs) vary widely, and studies based on these data are plagued with unintentional bias. Accurate prevalence data are paramount for any physician who counsels patients with intracranial aneurysms on rupture risk and treatment. We therefore sought to determine a more accurate number for the true prevalence of UIAs.

Background: Whereas mechanical thrombectomy (MT) has become standard-of-care treatment for patients with salvageable brain tissue after acute stroke caused by large-vessel occlusions, the results of MT in patients with medium-vessel occlusions (MEVOs), particularly in the posterior cerebral artery (PCA), are not well known.

Methods: Using data from the international Stroke Thrombectomy and Aneurysm Registry (STAR), we assessed presenting characteristics and clinical outcomes for patients who underwent MT for primary occlusions in the P2 PCA segment. As a subanalysis, we compared the PCA MeVO outcomes with STAR's anterior circulation MeVO outcomes, namely middle cerebral artery (MCA) M2 and M3 segments.

Understanding Adult Central Nervous System Hemangioblastomas: A Systematic Review.

World Neurosurg

November 2024

Semmes Murphey Neurologic & Spine Institute, Memphis, Tennessee, USA; Department of Neurosurgery, University of Tennessee Health Science Center, Memphis, Tennessee, USA. Electronic address:

Background: Adult hemangioblastomas (HBs) are rare World Health Organization central nervous system (CNS) grade 1 tumors, particularly affecting the posterior cranial fossa. They exhibit a gender bias, impacting men in their fifth and sixth decades of life and manifesting sporadically or as part of von Hippel Lindau disease. Understanding the intricacies of CNS HBs is crucial for clinical decision-making.

Article Synopsis
  • This study is a retrospective analysis of data collected from patients who underwent surgery for low grade spondylolisthesis, aiming to identify factors that predict delayed improvement post-surgery.
  • Among the 436 patients included, most experienced quick clinical enhancements, but about 21.4% showed delayed recovery, reaching the minimal clinically important difference (MCID) at 12 months rather than 3 months.
  • Key factors linked to this delayed improvement were poorer pre-surgery walking ability, better initial pain scores, and worse leg pain scores at the 3-month mark.*

Advancing diversity in spine surgery: the critical role of professional societies and foundations.

Spine J

July 2024

Department of Neurological Surgery, Semmes-Murphey Clinic, Memphis, TN, USA; Department of Neurological Surgery, University of Tennessee Health Science Center, Memphis, TN, USA.

This manuscript examines the challenges and initiatives within organizations associated with spine surgery to enhance diversity, equity, and inclusion (DEI), focusing on the systemic barriers that hinder the representation of women and underrepresented in medicine (URiM) minorities. Highlighting the contributions of pioneering individuals who overcame racial and gender discrimination to forge paths in these fields, it stresses the importance of professional societies and foundations in promoting DEI. Despite advancements, legal challenges and recent legislation in various states threaten to undermine DEI efforts, presenting a critical moment for organizations to reassess and reinforce their strategies.

Complex intracranial aneurysms: a DELPHI study to define associated characteristics.

Acta Neurochir (Wien)

July 2024

Endovascular Neurosurgery, Guido Guglielmi Endowed Chair in Endovascular Neurosurgery, Unicamillus International University of Health Sciences, Rome, Italy.

Purpose: Intracranial aneurysms present significant health risks, as their rupture leads to subarachnoid haemorrhage, which in turn has high morbidity and mortality rates. There are several elements affecting the complexity of an intracranial aneurysm. However, criteria for defining a complex intracranial aneurysm (CIA) in open surgery and endovascular treatment could differ, and actually there is no consensus on the definition of a "complex" aneurysm.

Intramedullary pediatric low-grade glioma of the spine.

Childs Nerv Syst

October 2024

Department of Neurosurgery, Johns Hopkins University, Baltimore, MD, USA.

Purpose: Pediatric intramedullary spinal cord low-grade gliomas (pLGGs) are rare diagnoses among central nervous system (CNS) tumors in the pediatric population. The classic presentation of the patients includes some degree of neurologic deficit, although many times the symptoms are vague which leads to delayed diagnosis.

Material And Methods: The first step in the diagnosis includes special parameters in spinal imaging, particularly magnetic resonance imaging (MRI), and surgical resection remains the cornerstone for both diagnosis and treatment.

Article Synopsis
  • The study investigates the outcomes of endovascular thrombectomy (EVT) for medium vessel occlusions (MeVOs) in different brain areas by analyzing data from an international registry.
  • Researchers analyzed 1,744 cases of isolated MeVOs treated between 2013 and 2022, observing different success rates for occlusions in specific vascular territories.
  • Results showed that A2/A3 occlusions had significantly poorer outcomes in terms of the 90-day modified Rankin score compared to M2 occlusions, while P2/P3 occlusions had lower rates of successful recanalization and increased early neurological deterioration.

Article Synopsis
  • This study examines how geographic differences and segregation in healthcare facilities affect the treatment of aSAH among Black patients compared to White patients.
  • The analysis of data from 2016 to 2020 showed that higher segregation rates in certain regions were linked to decreased mortality and increased use of tracheostomy tubes, but lower access to palliative care for Black patients.
  • Understanding these disparities is crucial for addressing healthcare inequities and improving outcomes for marginalized communities.

Low-grade gliomas are the most common brain tumor of childhood, and complete resection offers a high likelihood of cure. However, in many instances, tumors may not be surgically accessible without substantial morbidity, particularly in regard to gliomas arising from the optic or hypothalamic regions, as well as the brainstem. When gross total resection is not feasible, alternative treatment strategies must be considered.
